The Mixtec spoken in Magdalena Peñasco
has three tone levels, plus three different floating tones,
high, low, and limited high, which occur at the end of a word and affect the tone of a following word.
In addition, a high tone on the first syllable of a root may be either weak or strong;
weak high tones change to low following a low tone. In addition to several regular processes involving tone
spread and movement, there are a number of irregularities in the way these tone changes are realized in
certain roots. A short analyzed text shows most of these tone changes in a normal language context.
The paper also includes a brief comparison with the tone systems of other varieties of Mixtec in the
Tlaxiaco area, and with the Mixtec of the Colonial period.
